Special Issue Information

Dear Colleagues,

Metal matrix composite coatings have unique properties. Both the matrix and reinforcing phase type, as well as the method of production influence final application in the industry. Hard and refractory reinforcing phase (like carbides or borides) or self-lubricating particles contribute to increasing the performance parameters. This kind of coating may be obtained using laser processing like laser cladding or laser metal deposition, as well as using other surfacing methods or sintering. During all these processes, interesting physicochemical phenomena can be observed. The mechanical and microstructural properties obtained by these innovative processes are also important.

We invite researchers to contribute to this Special Issue on “Modern Metal Matrix Composite Coatings Reinforced With Carbides, Borides, Hard Phases and Self-Lubricating Particles”, which is intended to serve as a unique multidisciplinary forum focused on the production, properties, as well as applications of composite coatings reinforced with hard phases or self-lubricating particles. In particular, the topic of interest includes, but is not limited to:

  • modern production methods of composite coatings;
  • laser processing of coatings;
  • microstructural analysis of modern composite coatings;
  • laser cladding and laser metal deposition;
  • scanning electron microscopy in coating testing;
  • additive manufacturing;
  • arbides and borides in coatings;
  • self-lubricating coatings;
  • corrosion resistance of coatings;
  • wear resistance of coatings;
  • phase and chemical composition analysis of coatings;
  • microhardness and nanoindentation analysis

The paper presents study results focused on the microstructural, mechanical, and physicochemical properties of B-Cr coatings obtained by means of modification of diffusion borochromized layers by diode laser beam. The studies were conducted on 145Cr6 tool steel. Diffusion borochromized layers were produced at 950 °C in powder mixture containing boron carbides as a source of boron and ferrochrome as a source of chromium. In the next step these layers were remelted using laser beam. Powers: 600, 900, and 1200 W were used during these processes. The microstructure, microhardness, chemical composition, as well as wear and corrosion resistance of newly-formed B-Cr coatings were determined. As a result of laser beam interaction, the diffusion borochromized layer was mixed with the steel substrate. The study showed that too low laser beam power causes cracks in the newly formed B-Cr coating, and on the other hand, too higher laser beam power causes deep remelting resulting in the loss of microhardness. The reduced corrosion resistance in comparison with diffusion borochromized layers was caused by occurrence cracks or deep remelting. For B-Cr coatings produced using laser beam power 600 W, a small decrease in wear resistance was observed, but note that this coating was much thicker than diffusion borochromized layers. On the other hand, laser beam power of 1200 W caused a significant decrease in wear resistance. Newly formed B-Cr coatings had an advantageous microhardness gradient between the layer and the substrate. Full article
